I really don't know what to say...I mean I have heard of gas stations putting extra cleaners in the gas during the winter, this may induce your economics a tad, but wow, you guys are pulling awful numbers. Did this occur recently, or was it progressive? i.e. after it got cold, did your numbers start going down hill? Also, are you guys pulling any codes, i.e. running in lean mode? I, myself, do not know what to suggest for your guys' situation, perhaps someone w/more experience will chime in! Good luck guys!
